Rated 5 out of 5 by Rexx High performance, quiet, efficient furnace The SLP98V is a highly efficient, quiet, high performance furnace. With a 98% efficiency rating for propane or natural gas is phenomenal. Converted from Oil heat to propane with a 18% increased efficiency rating not even factoring in the efficiency of the modulating system. Instaled a combination unit with heat pump and A/C for all season home comfort management. The dynamic thermostat monitor has multiple seasonal programs and times for personalized efficiency by home life. The thermostat even includes outside temperature, humidity and temperature settings. Highly recommend the combination units. November 16, 2012
Rated 5 out of 5 by Mark1105 This furnace is high efficiency It is summer so we have not needed to turn it on. But from the information we have received it is a top of the line furnace with high efficiency. August 29, 2014
Rated 5 out of 5 by butchrx Quiet and efficient Have 2 of these, one is 2 years old and the other is 2 months old. Both are very quiet and efficient. I am waiting for winter to return to finally evaluate the newer system, but the other is wonderful during A/C weather and even better during the winter. We use propane for heating and it is pretty expensive. Last winter was colder than normal for us, but my propane usage was less than normal. Since I have now replaced my older, less efficient furnace with the second Lennox unit, I expect this winter's cost to be even lower. August 29, 2014

Rated 5 out of 5 by Parsgreat Silent and sweet! This has been a great furnace so far providing very even heating throughout the house. It is almost noiseless when running. We leave the fan on at all times and cannot hear it. It has provided a high level of comfort that we had not had for the first ten years in our home. Thanks Lennox August 23, 2014

Rated 5 out of 5 by jdkohn Even temperature This furnace lives up to its billing. It is the quietest furnace I've ever heard. It brings the temperature up so evenly and cools the same. I am glad I invested in this furnace. I would recommend this unit to anyone in the market for a new unit. August 11, 2014
Rated 5 out of 5 by Don45 Lennox furnace review We choose this furnace for its variable speed blower motor. We live in a hot climate so heating was not as important as cooling efficiency although this unit does have a two stage level of heating. The unit is very quiet and most of the time runs at a low speed to cool the house. We can hardly tell if the unit is running or not. The house temperature never varies no matter how hot it is outside. August 8, 2014
*This chart depicts potential energy savings you can expect from the SLP98V furnace, versus older furnaces with lower efficiency ratings. Criteria used in this example are 2,000 full-load heating hours, with a 60,000 Btuh heating design load and $1.368 ccf for gas. Your actual savings may vary, depending on the weather patterns in your local area, local fuel rates and your individual lifestyle.
